An applicator is provided for dispensing a first and a second protein solution to form a biological adhesive where the solutions can be deflected by a deflection assembly during dispensing for the adhesive to cover a broad or limited area. The applicator includes a housing having a housing head for enclosing therein a first reservoir containing a first component, and a second reservoir containing a second component. The first and second components are preferably fibrinogen and thrombin which intermix with water to form the first and second protein solutions, respectively. The housing further includes an elongated body portion defining a longitudinal axis for enclosing therein a conduit assembly having a first and a second conduit in communication with the first and second reservoir, respectively. The solutions intermix on an application site to form a fibrin sealant. In an alternate embodiment, the applicator includes two valves.
